摘要
Abstract
The hindered phenolic antioxidant was synthesized with 3-(3 ,5-di-tert-butyl-4-hydroxyphenyl) propionic acid and n-butyl alcohol as raw materials by esterifying reaction .The antioxidant characterized by infrared spectroscopy and HNMR was 3-(3 ,5-di-tert-butyl-4-hydroxyphenyl) n-butyl propionate .The optimal synthesis conditions were as follows :reflux time 8 h , the molar ratio of 3-(3 ,5-di-tert-butyl-4-hydroxyphenyl) propionic acid to n-butyl alcohol 1∶2 and the catalyst amount 3 .2%on the total reacts .The effects of hindered phenolic antioxidant on the protective effect of NR vulcanizates were studied by mechanical property testing , infrared spectroscopy , thermal analysis . These results indicate that the hindered phenolic antioxidant havepronounced anti-aging properties ,which is higher than those of BHT antioxidant .Besides ,the synthesized hindered phenolic antioxidant had no color pollution for rubber .关键词
